A magazine asks its readers to complete a survey on their favorite music and tv celebrities. Classify this sample

All the elements in the sample share a common characteristic. All of them read the magazine, so we may have a biased sample. And we also have the bias of the fact that only the volunteers will respond to this survey, so this is a biased sample.

This type of sample is usually called convenience sampling, where the elements in the sample are the most readily available (and what is most readily available for a magazine than its own readers?)

Then the type of sample is a convenience sample and a biased sample.

2.   2 3/5.

3.   2 1/2.

step-by-step explanation:

6 - 3 2/5

= 2 3/5 (answer).

5 1/4 - 2 3/4

= 21/4 - 11/4

= 10/4

= 2 1/2 (answer).
